With ignition on, bike not running. Press the info button on the controls it will bring up temp, oil pressure, EITMS. Roll your throttle forward for a few seconds and the EITMS will change from enabled to disabled.
You can roll the throttle forward while stopped and engine running, hold it there until your cruise indicator flashes orange. If it flashes green, do it again; green is on, orange is off. Or you can do as said above by going into the menu on the infotainment system and disable it there by unchecking the box. Bike running or not running doesn't matter but you have to be stopped.
